All Tech Insulation Cellulose System is ideally suited to providing additional R-value over existing insulation, as it completely fills voids and gaps open by other forms of insulation. All Tech Insulation Cellulose System also can be installed in existing uninsulated exterior walls through various methods. There is no cutting, no fitting and no hauling insulation up to the attic. Just pour it in and blow it out.   Top of page   What are the thermal benefits of All Tech Insulation Cellulose System? All Tech Insulation Cellulose System is a denser product, providing better barrier protection to reduce air infiltration and convection currents. All Tech Insulation Cellulose System fills gaps and voids eliminating air leaks. All Tech Insulation Cellulose System has a higher R-value per inch than most other types of insulation. This means more insulating with less material and less money. All Tech Insulation Cellulose System will not lose thermal value over time. Accelerated aging tests (CAN/CGSB-51.60 M-90) performed on All Tech Insulation Cellulose Solution have shown there is no noticeable degradation over time. All Tech Insulation Cellulose System also retains R-value in cold temperatures. Top of page   What is R-value? (also see Insulation Factors K, C, U, R page) R-value is the standard for measuring a material's insulating power. The higher the R-value, the better the material insulates. All Tech Insulation Cellulose System has a higher R-value per inch than other insulating materials, according to the US Department of Energy The R-value Rule: R-value means resistance to heat flow. The higher the R-value, the greater the insulating power. Compare insulation R-values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate, the type and size of your house, and your fuel use patterns and family size. If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-value, it is essential that this insulation be installed properly. The Federal Trade Commission R-value rule and accepted industry standards require All Tech Insulation Cellulose System to be specified and sold at settled density. All Tech Insulation Cellulose System coverage charts indicate the amount of material that must be installed to produce the specified R-value-settling is already built into the charts. R-value is one factor that affects the energy efficiency of a home. Studies of actual buildings show that All Tech Insulation Cellulose Solution-insulated buildings use as much as 26% less energy than similar buildings insulated with other insulations at the same R-value. One reason for this is the ability of All Tech Insulation Cellulose System to control air infiltration.   Top of page   What are the sound control benefits of All Tech Insulation Cellulose System? The same density in All Tech Insulation Cellulose System that protects you in a fire absorbs the noise you don't want to hear. All Tech Insulation Cellulose System's ability to fill gaps and voids creates a quieter home by reducing noise transmission. All Tech Insulation Cellulose System is approved as an enhanced sound control material for homes located in airport flight paths. All Tech Insulation Cellulose System has a Noise Reduction Coefficient (NRC) of 0.90 according to ASTM C-423-84a. All Tech Insulation Cellulose System suppresses sound transmission because the density is two to three times greater than other insulation products, completely filling any cavity into which it is properly installed. All Tech Insulation Cellulose System eliminates voids and gaps that are convenient avenues for sound to travel. Top of page   Is All Tech Insulation Cellulose Solution safe for the environment? All Tech Insulation Cellulose System consists of 85% recycled paper fiber, at least 80% recovered, post-consumer paper content. All Tech Insulation Cellulose System is not manufactured with any formaldehyde, asbestos, mineral fiber or fiberglass. The borates added to All Tech Insulation Cellulose System to provide flame resistance are six times less toxic to humans than common table salt. The average home insulated with All Tech Insulation Cellulose System recycles the equivalent of 460 Wall Street Journals and prevents atmospheric release of 598 lbs. of carbon dioxide emissions. Newsprint is one of the largest single components of the residential waste stream. Insulating a typical 1,500-sq. ft. ranch-style home with All Tech Insulation Cellulose System productively recycles as much newsprint as an individual will consume in 40 years. This is based on data from the National Solid Waste Management Association. If America's homes were insulated with All Tech Insulation Cellulose Solution, over 3.2 million tons of waste newsprint would be removed from the refuse stream every year and put to productive energy use conserving vital energy resources. This projection is based on 1.5 million new homes with an average area of 1,500 sq. ft, insulated to R-30 in the attics and R-13 in the sidewalls. If more stringent standards, such as those of the Model Energy Code were followed, even more recyclable material would be removed from the waste stream. All Tech Insulation Cellulose System is produced in electrically driven mills, requiring less energy to produce. Other types of insulation are produced in furnaces that use natural gas and release greenhouse gases.

Use soffit vent baffles to allow the soffit to stay open above the insulation for proper air flow. Insulate the inside of the access hole cover with batt or foam board insulation to complete the job. CAUTION: To help avoid fire: Keep insulation at least 3 inches away from the sides of recessed light fixtures. Do not place insulation over such fixtures so as to trap heat. Also keep insulation away from exhaust flues of furnaces, water heaters, space heaters or other heat-producing devices. To be sure that insulation is kept away from light fixtures and flues, use a barrier to permanently maintain clearance around these items. Check with local building or fire officials for guidance on installation.   If you don't see your solution listed, contact an All Tech Insulation engineer today (432-897-1533) for a deeper discussion about your insulation requirements.
